Recent advances in energy storage with graphene oxide for supercapacitor technology

Generally, graphene oxide (GO) has emerged as a promising material for revolutionizing supercapacitor (SC) technology due to its exceptional properties and versatile characteristics. This review explores the potential of graphene oxide in enhancing the performance and energy storage capabilities of SCs. GO, a two-dimensional (2D) nanomaterial derived from graphite, exhibits remarkable electrical conductivity, high surface area, and excellent mechanical strength. These attributes make it an ideal candidate for SC electrodes, enabling efficient charge storage and rapid energy release. The functional groups present on the GO surface offer enhanced solubility and ease of processing, facilitating its integration into SC devices. Furthermore, the tunable properties of graphene oxide allow for precise control over the electrode's surface chemistry and morphology, leading to improved capacitance and charge–discharge rates. GO-based SCs demonstrate superior energy and power densities compared to conventional energy storage systems, making them ideal for applications requiring quick energy bursts or high-power output. Moreover, the compatibility of graphene oxide with various electrolyte systems and its exceptional stability contribute to the long-term reliability of SCs. Additionally, the abundant availability and cost-effectiveness of GO make it a viable alternative to expensive and resource-intensive materials currently used in SC technology. In conclusion, GO holds significant potential in advancing SC technology, offering enhanced energy storage capabilities, improved performance, and cost-effective solutions.
